Design and Implementation of Speech Recognition System Based on Artificial Intelligence

Speech recognition technology based on artificial intelligence AI technology has gradually been widely used under the background of the continuous development of current data processing technology, and belongs to the branch of biometrics technology. AI-based speech recognition technology can be applied to biometric recognition and matching in different fields, providing technical support for the intelligent development of various industries and fields. In car intelligent voice recognition system, for example, for the car voice recognition system speech recognition real-time and accuracy requires high characteristics, the article adopts multiple pickup as car voice system sound acquisition hardware system, the voice data pretreatment after feature extraction, in artificial intelligence AI technology and sound biometric matching model and alarm sensitive words. In addition, the sensitive word recognition transmission system is connected to the cloud platform of the public security alarm system to realize intelligent voice recognition alarm. In addition, the dialect speech library of different regions was established, 60 experimental subjects from different regions were selected, and 5 alarm sensitive words were spoken in dialect for the experiment.
